a. An M20C aircraft are powered by a Lyc~ming_O-360-A1D engine equip_Ded with a constam-speed propeller,

b, M20D aircraft (1963) are e~ipped with a Lycoming 0-360-AlD engine~having a governor control

c. M20D aircraft (1964 thru 1966) are ec~ip_oed with a Lycoming 0-360-A2D enginehaving a fixed- The 0-360-,41D be installed as oDtiondl ~c. pitch propeller. engine may I-~0 d. Lycoming 0-360-A1D and 0-360-A2D engines are both rated hp at 270~rpm.

e. All M20E aircraft are powered by a Lycoming 10-360-.4W engine rated 200 hp at 27(30 rpm.

f. An M20E aircraft are orovided with a ram induction air source. Filtered air is used during takeoff, ~andLng, and under dusty conditions. Air source selection is made by man- ual control, An emergency fn_c~uction air source is provided; in ti,e event of filter icing, a spring- loaded valve, located behind the filter inside the engine compartment, will open automatically to maintain air flow;o the engine. To Drevent ice iorma~fon in the induction system, the power boost control must be set for ffltlred air ii icing conditions are present,

2. PROPELLER

Those models with constant-s_oeed propellers have low pitch setting capabilities for maximum take- on' power. Propeller pitch is regulated by an engine-mounted governor that insures maximum power efficiency at cruising speeds, Engine oil pressure actuates the pitch changing mechanism.

3. WZNG

All M20 series aircraft have laminar-flow wings. Laminar air flow over the wines is insured by I'lush rivets attaching the leading edge or'the "wraD-around" wing skins. Wing construction features multiple ribs attached to main and stub s_Dars incorPorating aluminum spar caps.

4, ~TSEL4GE

The cabin suDersuucmre is built of 4130 ntb~ilar steel and covered with non-structural aluminum skins. The taTZ section (baggage com_oanmem and aftstruoture) has a stressed-skin semi-monoco$re design. Aluminum skins are riveted to heat-treated alumimun bulkheads with extruded aluminum stringers reinforcing the tail cone sectioh

5, EMPENNAC~

The empennage is constructed on qDtically aligned jigs to insure uniformity and close tolerance fit for all parts. Construction is of sheet metal, riveted to formed ribs and s_Dars. To provide srabi- lizer trim, the entire empennage pivots around the tail cone attachment points.

6. LANI~INCGEAR

The landing gear is unicpe in ~hat it is manually retracted by the pilot. Gear-assist s_Drings in the wings, aided by bungee springs in the fuselage, make manual o_Deration of the gear cIuite simple. Gear-mounted rubber discs are used for shock absorption. Grease fittings are provided at important lubrication points on the landing gear, The standard M20D has a fixed landing gear, but can be con- verted to a retractable gear identical to the M20C gear system. Electrically ooerated gear retrac- ing systems are optional for all models.

7. ~RAKESYSTEM

aydraulic disc brakes are featured on all models. The hydraulic fluid reservoir is located in the inside upper left-hand area of the firewall. Toe-actuated rudder_oedals operate the left and right main gear brakes independently. Dual brake systems are optional for all models.

1-2

Island Enterprises 8. FL3GHT CONTROLS

The ailerons, elevators, and rudder are of an all-metal jig-built construction incorporating hinges of machined extrusions, Push-pulltubes, rather than the conventional cable systems, are used to actu- ate the control surfaces.

9. FMPSYSTEM

The wide-span all-metal flaps are hydraulically controlled by a hand-operated pump which actuates a hydraulic cylinder., it relief valve is provided which releases hydraulic pressure at a slow rate as retraction springs (or air pressure) raise the naps. Ihehydra~lic fluid reservoir is common to both the brake and flap systems. Maintenance of the fla_o system is similar to the brake system.

10, TRIMSYSTEM

X small control wheel on the floor between the front seats actuates the adjustable stabilizer via a ~ar reduction box and torque tube Linkage which actuates the empennage jack screw. The torcIue tubes are connected by universal joints and are supported by-formica guide blocks.

11. NELSESTEM

The fuel system consists of integral fuel tanks located in the front inboard portion of each wing. These tanks are Formed by setling off a portion of the wing through the use of a special sealir;g com- pound. Fuel is fed from the wing, to a tank selector valve, on to an electric boost pump and then to the engine-driven iuel_oumo and fuel injector or carburetor.

12. mSTEM

The electrical system is provided with a 50-amp 12-volt generator and a 3S-amp/hour battery. AII electrical systems can be turned off with the master switch which actuates a relay located at the battery, Circuit breakers are provided on the lower right side of the instrument panel. Standard equipment includes a 250-watt landing light, navigation lights, interior lights, an electric starter, gear and stall warning systems, and an electric boost pump.

13, INSIlltTMENT \NEL

The instrument panel has been designed to provide functional location of all flight, radio, and engine instrument grouDs, The flight instiumems onthepilois side are installed in a rubber shock-mounted Danel to reduce;ibrztion transmission to the instruments.

14. HEATING, VENTIL~TION. AND DEFROSTING mSTFMS

Cabin heat is obtained from a muff which surrounds the engine exhaust manifold. From the muff a flexible duct transmits heated air to a junction box zft of the firewall on the co-pilors side. Cold air is also ducted to this junction box from the flush air scoop on the right side of the airplane. The hot and col~ air entering the junction box can be controlled to provide the combination required for the desired tem_Derature. From the junction box, air is ducted to the piler and co-pilot's feet, wind- shield defroster, and rear cabin.

15, SZ.iiTS

X11 seat backs are contour formed. The seats are padded with plastic polyfoam and covered with durable u_dnolstery. The from seats have a three-position reclining adjustment and are adjustable fore and air on the floorboard seat rails. The rear seat back may he removed to provide a larger cargo area.

HAND LING AND SERVICING

Island Enterprises SECTION II HANDLING SERVICING

A. GENERAL

This section provides ground handling and servicing instructions.

B. ACCESS PROVISIO~S

Figure 10-1 shows the location of the access panels and plates that provide access for purposes of service and maintenance.

C. HANI)L3h~G

The following instructions are recommended to avoid damage to the airplane during ground opera- tions. If improperly handled, extensive damage to the airplane and its equipment may result. The airplane may be taxied as required for normal maneuvers. Brakes or rudder pedals may be used for turning. If a towbar is used, one man may move the airplane providing it is on a fairly smooth level surface. Points where pushing the airplane are permitted are leading edge of the wing, wing tips, and the inboard position of the propeller blades adjacent to the propeller hub,

i. Jacking

When it is desired to raise the airplane off the ground to check operation of the landing gear, the following jacking procedure is recommended. By using jackpoints provided outboard of each main gear (Figure 2-1), it is possible to use standard aircraft jacks to raise the main gear off the ground. A yoke-frame jack may be used under the propeller. Care must be taken not to damage the pro_Deller or spinner. The nose may also be raised by anchoring the tail skid tfe- down ring to a fixed point in the shop floor while jacking the aircraft at the wing hoist points.

2. hiooring

When mooring aircraft, the following method is recommended. Place chocks fore and aft of each main wheel. Stakes may then be driven in the ground outboard of each main gear, approx- imately three feet, and at the tail skid location. Tie down rings are provided, two feet outboard of each main gear, at the jack point. A tiedown ring is also provided at the tail skid location.

3. Towing

A suitable towbar is provided as standard ec(uipment with each airplane. The lower bar of the towbar is placed t~rough the gear spindle upper crossmember. Care must be exercised that the nose gear is notrotatedpastits normalswivel angels. Towing with a tractor or by other mechani- means is not recommended.

Note: See that parking brake is off before towing airplane.

Remove two strainers (Figure 2-7) and flush with kerosene every 50 hours or each time oil is changed. (MZ0E&F)

3. BRAKESYSTEM

The brake cylinder reservoir must be filled with the brake fluid specified in Figure 2-9. The reservoir fluid level should be checked at every 50-hour inspection and replenished as necessary. After a periodic installation, the brakes require no adjustment during the serv- ice life of the brake lining.

CAUTION: Do not fill reservoir while parking brake is set or when flaps are extended. (See page 5-15 for brake bleeding procedure.]

4. BATTERY

Check battery fluid level and battery condition every 25 hours. Use only distilled water when servicing; avoid comaminarion of cells.

5. INDUCTION SYSTEM

Check air filter visually at each pre-flight inspection. If cleaning is necessary, remove filter and clean in accordance with Section III C. Check power boost door seal(MSOE&F).

6. VACtUM STEP SYSTEM (1965 Models and subsequent)

A vacuum servo will raise the stC~p when the engine is started and sufficient vacuum is Produced. A spring will pull the step down when the engine is stopped and vacuum is relieved (Figure 2-8).

NOTE: To lubricate the step strut, spray a light coat of a Silicone-type lubricant on all four sides of shaft. This substance will not attract dust or soil clothing.

E. LUBRICATION

Refer to Lubrication Diagram (Figure 2-9) for instructions regarding lubrication points, intervals, and type of lubricant recommended. Crease finings are provided on the nose gear and main gear. Bearings used in bell cranks, hinge points, and rod ends should be l;bricated periodically to prevent corrosion. Avoid excessive application of lubricants. Excess lubricant onemerior surfacesof bearings tends to attract dirt and grit and may lead to malfunction of the unit.

Where a reservoir is not provided around a bearing, gpply the lubricant sparingly and wipe off ex- cess. Remove wheel bearings from the wheel hub and clean thoroughly with a suitable solvent. When repacking with grease, be sure lubricant enters space between rollers and retainer ririg. Do not pack grease into wheelhub. (See Fig~re 2-9 for recommended lubricant.)

Whenever specific instructions for lubrication of mechanisms are not available, observe the follow- ing precautions:

I. Apply oil sparingly, never more than enough to coat bearing surfaces. 2. At the regularinspection intervals, squeeze the magneto cam follower felts with the fingers. If oil appears on fingers, do not add oil to the felts. If felt is dry, moisten with light oil. Be careful not to add too much oil, because an excess will be thrown off during operation and will cause pining and burning of magneto points.

Refer to Lycoming Service Instruction 1014 (latest revision) for engine oil specifications.

Island Enterprises FI EXTERIOR ~NTERIOR CARE

As with any palm applied to a metal surface, an initial curingperiod is rec~ired to develop the desired ~Iualides of durability and appearance. Therefore, wax or polish should not be applied to the exterior until two or three months after delivery. Wax substances will seal the paint from the air and prevent curing. Hold buffing to a minimum until curing is complete and there is no danger of disturbing the undercoat.

Before washing the e9terior, be certain the brake discs are covered, thepitot shield is in place. and both static air buttons are masked off. Loose dirt and mud deposits should be flushed away aircraft before washing the exterior with an detergent and cool water. Use soft cleaning cloths or a chamois and avoid harsh or abrasive detergents thatmight scratch or corrode the surface. To remove a heavy oxidadon film, use a prewar cleaner (example: HarlyCarnuba). For nonoxidized or pre- cleaned surfaces, apply a good exterior-finish wax (example: Harry Wax) recommended forpro- tection of acrylicenamel finishes. Follow the manufacturer's instructions carefully. Aheavier coating of wax on the leading edges of the wings, empennage, and nose section willhelp reduce drag and abrasion in these areas.

If fuel, hydraulic oil or any other fluid containing dyes ia found on the exterior paint, wash the area at once to prevent staining. Spilled battery acid must be flushed away immediately and the area treated with an alkali and water solution followed by a thorough washing with an aircraft detergent solution.

Household window cleaning compounds are not recommended, as some contain abrasives or sol- vents which could harm the Plexiglas. Furthermore, it is essentialthat allcleaningcompounds and application cloths be free ot abrasives, grit, or otherforeignmaaer. Never usedenantred alcohol, benzene, carbon tetrachloride, acetone, or leaded gasoline for cleaningPlexiglas or in- terior plastics. Before wiping the window surfaces, flush the exterior with clear waterto remove panicles of dirt. Grease or oil can be removed by wiping the panel with a cotton cloth saturated with unleaded gasoline or kerosene. An anti-static Plexiglas cleaner is recommended for cleaning and polishing the windshield and windows.

Normal household cleaning practices are recommended for routine interior care. The seats, rugs, upholstery panels, and headliner should be frequently vacuum cleaned to remove as much surface dust and dirt as possible. The fine leather or vinylupholstery and kickpanels need occasional washing with an aircraft deteroent solution to prevent the working of dirt into the surface. Wipe clean with a slightly damp cloth and~rywirha soft cloth. Never apply furniture polishes. Foam type sham- poos and cleaners (example: Garry's VLP) for vi?yl, leather, and plastic materials can be used to remove stains and to condition the entire interior. Spray-on dry cleaners are also recommended.

When using commercial cleaning and finishing com_oounds, carefully follow the manufacturer's in- structiorts. Never saturate fabrics with a solvent which coulddamagethebaciting andpadding materials. To minimize wetting of carpets, keep foam as dry as possible and rub gently in circles. To remove foam, use a vacuum cleaner. Royalite, vin~jl, and metal surfaces may be cleaned with a damp cloth or an aircraft detergent solution. Do not use alcohol or strong solvents on Royalite plastics.

A. GENERAL

The M20C and M20D are powered by a Lycoming 0-360-A1D, 180 hp engine. The standard M20D is equipped with a Lycoming 0-360-A2D, 180 hp engine, the 0-360-AlD engine being optional for a con- stant-speed propeller, Both engines have a compression ratio of 8.5:1 and require a minimum grade of 91/98 octane fuel.

The M20E is ecpipped with a Lycoming 10-360-A1A, 200 hp engine having a constant-speed all-metal propeller. This engine must be serviced only with a fuel having a minimum grade of 100/130 octane.

Two Bendix magnetos are furnished, the left magneto being ecluipped with a set of retard breaker points for a starter vibrator which furnishes long duration, boosted spark for starting. The ignition switch combines both starting and ignition functions. To supress radio static, shielded spark plugs and ignition harness is furnished as standard equipment.

For derailed engine and propeller information, refer to manufacturers' handbooks,

B, TROUBLE SHOOT~G

Refer to the a_bpropriate Lycoming or Bendix manual for engine trouble shooting procedures.

C, AIR FILTER CARE

The incorDoration of an induction air filter in the engine air intake system significantly increases engine lifd. Dust panicles accumulate on the filter element and must be removed every 25 hours, or more frequently in dusty atmospheric conditions, to prevent obstruction of air intake during engine operation.

To clean induction air filter (paper element): i. Removefilter from aircraft. 2. Direct a jet of air up and down the entire filter element lair nozzle must he kept at least 2 inches from filter). 3. Inspect filter for damage, holes, and presence of rec~uired gaskets before reinstalling.

To clean air-maze toil) type filter: i. Removefilterfrom aircraft. 2. Washinsolvent. 3. Apply a light coating of lubricating oil. 4. Reinstall onaircraft.

A. GENERAL

The landing gear is a tricycle gear type. It is constructed of~eavy, chrome-molydenum tubular ste~ heat treated for greater strength and resistance to wear. Neoorene rubber discs absorb the shoc8 of normal taxiing and landing. The attaching points of the main gear are in metal bushings embedded in the gear-mounting box and attached to the soars. The nose wheel is mounted to the cabin's tubular-steel frame. The main gear wheels are eciuipped with hydraulic brakes.

Island Enterprises 3. Instructionsfor ri~,oingnosegeardoors.

a. Raise airplane off of ground by method described in Section n-C-I.

b. Connect gear door links to gear doors (upper holeinbracket). Gear retracrionsystem must be rigged before gear doors can be rigged properly.

c. Gear doors must be timed td open and close correctly without contactingthe gear. On 1962-1964 models, timing is accomplished by adjusting a screw on the cam. Turning the screw clockwise speeds closing. Turning the screw counterclockw;se slows closing.

d. M-20C E Models (1965 gr OrJ) incorporate door retraction arms on the nose gear retrac- tion truss. To rig nose gear doors, adjust links shown in Figure 5-4.

e. Doors must be checked for a tight fit when in c~e closed position. Play may be taken up by adjusting the gear door links.

f. If the gear, in the retracted position, prevents the doors from closing completely, the ec- centrics on the retract truss must be reset to raise the gear in the wheel well. The same applies for lowering if the gear is retracted too high in the wheel well. NOTE: if item "f' is incorporated, items "c" and "e" must be repeated.

E. BRAKE ANDWHEELMAINTENANCE

i. Braltelininginspectionand replacement (FigureS-5).

Visually inspect the brake while it is insta~ed on the airplane. No adjustment of brake clear- ance is necessary. If, after extended service, the brake linings become excessively worn, re- place with new linings as follows:

a. Removedustcover fromwtieel.

b. Remove spindle nut from one side of wheel and two bolts from the other side (2 bolts that hold back brake plate stationzry).

c. Slide wheel out and remove pressure plate that has the worn lining on it.

d. The linings can easily be replaced by drilling out three rivets from thepressureplate and three rivets from the back plate.

Island Enterprises 2. BrakeBleeding.

When braking action becomes spongy and erratic or when repairs require the replacement of actuating components, it will be necessary to bleed che hydraulic brake system. Sest results are achieved with the use of a hydraulic fluid system bleeder (pressure poi) pressurized with air to approximately 35-40 Ibs. When bleeding dual brake systems, both the pilot's and co- pilot's brakes must he depressed alternately during bleeding to reposition the shuttle valves.

First, remove the vent cap from atop the firewall fluid re~ervoir and attach a fitting and hose that will carry expelled fluid from the reservoir to a clean catch pan positioned next to the hose section. Remove the rubber cap at one of the main wheel brake cylinder assemblies, open the valve by backing off the small center pin, and attach -~e pressure pot hose. Air bubbles in the fluid being expelled from the reservoir will give the stream a milky appearance. When the fluid Nos clear and transparent into catch pan, close the bleed valve, disconnect the pressure pot hose, and cap the bleed valve. Repeat the procedure with the other side of the system, After disconnecting the overflow tube from the reservoir, remove excess fluid from the reservoir through its side plug to re-establish the proper fluid level.

3. Wheel Assembly Inspection.

a. Placeairplaneonjacks (SeeFigureZ-l).

b. Remove axle nut and two bolts from back plate and slide the wheel off.

c. Check for bolt failure. Replace any bolts found to be defective (Figure 5-6).

d. Check the internal diameter of the felt grease seals. Replace the:elt grease seal if surface is hard or gritty.

e. Inspect the casting for visible signs of cracks or corrosion. If there are any indications of cracks, the tire and tube should be removed and the wheel disassembled for a closer in- spection.

f. Replace any wheel casting having visible cracks.

F. MANUALLANDING GEARRIGGINGPROCEDURE

The ~ar retraction system is designed to hold the gear down-and-locked only when the retraction linkage is in the overcenter configuration. Collapse of the gear, at landing or during taxiing, due to a disengagement of the locking mechanism, can be caused by improper adjustment of the overcenter lock mechanism or by disengagement of the retraction handle from its down-lock block under the instrument panel.

1. Rigging Instructions.

a. Raise airplane and remove access panels shown in Figure 5-10.

b. Remove retraction handle from gear-down lock. Tiehandle loosely to prevent bungee from forcing it down. In order to prevent damage to retraction tubes, do not move gear legs Trom outside until step C has been accomplished,

c. Disconnect retraction tubes at point B (Figure 5-10). Loosen hearing, check nuts on tubes at point E and on tubes at point A.

d. Check nose gear and main gears (2) for any binding at hinge points (Figure 5-10) while mov- ing gear legs back and forth by hand. Tubes may be disconnected at point C during checle of main gear. Lubricate gear retraction system at points indicated in Figure 2-9.

e. Place the retractionhandle inrhe gear-down lock. Check for and remove any foreign matter lodged between the retraction truss and retraction link connection at points Z Sas shown in Figure 5-11. Place all gears in the down-and-locked position. it is recommended th,7t C-clamps be attached at points X R (Figure 5-11) to hold the retraction truss firmly in the overcenter configuration.

REVISED OCTOBER 1972 5-15

Island Enterprises f. By turning tubes, adjust retraction tubes so that a 3/16" OD bolt can be inserted through re- traction lever and bearings at point B (Figure 5-10). This will give a zero preload in the system wit~ the handle in the gear-down lock.

g. By turning tubes, shorten retraction tubes two turns and lenghen retraction tubes two to two and one-half turns. Tighten check nuts (4) at points A and E (Figure 5-10).

h. Remove retraction handle from gear-down lock positipll and connect tubes. Replace retrac- tion handle in gear-down lock position.

i. Inspectionof System Preload.

a, Nosegear (seeFigureS-ll).

1. Place rigging tool (8442) on retraction link with sloped edge aft. Hold tool inplace against retraction link.

2, Placefinger atpointR.

3. Apply force on torcF~e wrench and read torque at the instant point R first begins to move. Movement of retraction truss may be felt at point R and may be seen in area of ~oint S. Practice this several times before recording torque. should be between 100 and 130 inch pounds.

NOTE: Take reading on torque wrench when .005 to .010 inch movement is observed at points R and X (Figure 5-11).

4. After release of force, retraction truss should snap back to full overcenter and should bear tightly against retraction link at point S, This should be carefully checked by pulling down on retraction truss. If retraction truss moves down, then the preload in tubes is not sufficient.

5. Eccentric bushings at point A on the nose gear retracting truss may be rotated as re- cluired to obtain the proper gear-up travel and proper gear door rigging.

CAUTION: Nose gear dowrlock rigging must be rechecked after eccentric bushings are changed.

b. Main Gear (see Figure 5-11).

1. Place rigging tool (8444) as shown in Figure 5-11. Hold in place with thumb at point Y pressing forward.

2. Placefinger atpointX.

3. Apply force on torcpe wrench and read tor~e at instant that point X first begins to move. Movement of retracting truss may be felt at point X and may be seen in area of point 2, Practice this several times before recording tor~e. Tor~e should be between 240 and 280 inch pounds. The difference in left and right gear tor~e should register within t25 inch pounds of each other.

4. After release of force, retracting truss should snap hack to full overcenter and should bear tightly against retracting link at poirit Z. This should be carefully checked by pulling down on retracting truss. If retracting truss moves down, the preload in tubes is not sufficient.

CAUTOOT: Do not attempt to rig the gear to increase or decrease gear-up travel.

5-16 REVISED OCTOBER 1972

Island Enterprises 3. ~djustmenr ofPreload.

If the torque values do not fall within the limits specified, then the system preload should be chan~Sed by changing the lenghs of retraction tubes. This is done by taking a turn on the rod end bearings in theprsper direction. One-half turn is usually sufficient. Any adjustment made to the nose gear should be made identically to both retraction tubes since they should carry the szme~reload.

Since the retraction rubes from all gears are attached to the gear retraction lever. a change in preload in the retraction tube at one gear can affect the preload in the retraction tubes at the remaining gears. Therefore, after an adjustment is made at one gear. the other gears must be rechecked. This process must continue until the proper preloads are obtained in the retraction tubes at all gears.

The amount of freedom of the gears las determined from the check made under item 4 of rigging instructions above) will affect the torque readings. Gear systems with free joints will be ade- quately rigged when the torque is on the low end of the range while the gears that are stiffer may require torque values on the high end of the range for adequate preload.

A final check should be made of the force required to place the gear handle in the gear-down lock (,oear extended position). If the force re~uired to move thegear handle forward the last one to two inches is escesshe, then the system prelozd may be reduced slightly within the prescribed torque limits. Check for and relieve any bind in the sliding hand grip at the top of the gear lever since a bind at this point may make it difficult to lock the gear handle in place.

SOTE: Gear rigging tools (8442, 8444, 8186) may bepurchased at a nominal cost through the ~iooney dealer and distributor organization.

1. RubberDiscs.

If a landing gear shock unit fails to pass the inspection described in Figure 5-12 5-13, t~e rubber shock discs must be replaced.

NOTE: A check of the nose gear shock unit can also be accomplished by checking the propeller clearance as follows: With the unloaded aircraft on a flat surface and the tires inflated to the proper pressure, a 74-inch propeller should have a minimum of 9 I/2 inches clearance from the ground. Less clearance may indicate that the rubber discs are r'.e- fective and that a more thorough check should be made.

2. Collars andBolts.

a. Inspect landing gear shock absorber bolts and collare(See Figs. 5-12 5-13) for deformation or indications of failure.

b. Remove collars and bolts at each annual inspection and check for bends, wear, and cracks. Replace if necessary. it is suggested that s_Dare pans be obtained prior to this inspection. I)o not replace a bolt without replacing the collar, or a collar without replacing the bolt.

c. See Figures 5-2 and 5-3 for removal of shock discs and collar.

3. Nose Gear Snubber.

A hydraulic shock absorber is installed on the nose gear of 1966 O?! ~IZOC,E,&F models. The shock absorber housing is sealed and the unit requires no maintenance. When worn to a degree that effectiveness is impaired, the entire unit should be replaced.

Island Enterprises H. ELECTRIC GEAR SYSTEM (OPTIONAL)

I. Operation.

T;ia gear retraction system is by the wheel-shaped switch knob on the upper portion of the flight panel. To raise the gear, the knob is pulled out and moved up to its upper detent. An "air switch" is incorporated in the electrical circuit which prevents landing gear retraction until a safe airspeed is ~ittained (See NOTE). The action of the system may be monitored visually by watching the movement of the indicator mark through the glass in the floorboard aft of the nose wheel well. A limit switch will stop the gear in its retracted position. To lower the landing gear, the is pulled out, moved down, and placed in the lower detent. A limit switch will stop the gear extension when the proper locking force has been exerted to hold the gear down. There are three ways to check that the gear is com- pletely down and locked: a. The green "safe-to-land" indicator light ton the left ~nel) will come on. b. The black indicator marks, as deen through the glass in the floorboard, will be aligned. c. No audible warning horn sound willbe heard when the throttle is retarded.

NOTE: An 80 mph air pressure equivalent must be applied to the pitot tube orifice to actuate the airspeed pressure switch which permits retraction of the gear. Attach a 12-inch length of 3/8-inch rubber hose (surgicaltubing) over the pitot tube end and pinch the open end of the hose with a cotter pin. Rotate the cotter pin until the compressed air in the hose activates the air switch.

2. Manual Operation of the Electric Landing Gear System.

a. Pull landing gear circuit breaker OFF. b. Put pear switch in the gear-down position. c~ Push crank engage handle forward. d. Crank clockwise approximately fifty (50) turns to lower the gear. e. Gear is down when green gear light is on-check gear position visual indication.

CAUTION: Do not retract gear with the manual handcrank. Use electrical retraction.

3. Electric Gear Inspection.

At each 100 hours of service, the electric gear system pivot points should be lubricated (See Figure 2-9) and test run with the aircraft on jacks (See Figure 2-1). Check the landing gear actuator for security of mounting, cleanliness, and indication of overheating or damage. Lubri- cate actuator ball screw with recommended lubricant every 100 hours.

a. After 500 hours of operation and each 200 hours thereafter: (1) Remove the actuator from the aircraft. (2) Remove the end cap and wipe excess grease from gears. (3) Visually inspect gears for wear as follows: With open end of actuator toward you, rotate jack screw shaft counter clockwise to remove all slack from ring and worm gears. ~Iake an index mark on one gear tooth and on the inside of housing. Turn jack screw shaft clockwise until ring gear contacts worm gear and check index marks. Visible wear or backlash of 1/2 tooth or more requires immediate replacement of gears. ALTERNATE PROCEDURE: Measure backlash by using a .025" diameter wire or .025" thick shim as a feeler gage. If feeler can be inserted between gear teeth replace gears. Repeat above prccedure after rotating the ring gear thru 900; Ie0O; and.2;00: Repack gear box with recommended lubricant. ~5) Reinstall end cap and resafety. (6) Reattach helm bearing to bellcrank (refer to page 5-24 Section 5, paragraph B for proper actuator adjustment and reinstallation instructions).

d. Perform retraction test through at least two trouble-free cycles. Check for: Proper limit switch adjustments. Position indicator adjustment and operation. Excessive friction or binding. Nose and main gear rigging. Main and nose gear door-to-jamb rigging.

REVISED OCTOBER 1975 5-23

Island Enterprises 5. Electric Gear Rigging Procedure.

a. Jack aircraft (See Figure 2-1) and remove access panel (See Figure 5-10). b. Disconnect all retraction tubes and the actuator helm end from the retraction bellcrank. Check the 7.50 actuator dimension (See Figure 5-14, Item 1). Adjust helm end as neces- sary to obtain the 7.50 dimension. Position the ball returns on the actuator barrel so that they face the actuator motor, then reinstall helm end on to the bellcrank.

NOTE: When installing helm bearing end in the bellcrank, position it freely so there will be no lateral bind on the jack screw. Place one AN960-716L washer next to the ball joint, (can be placed on either side) and shimremaining space with AN960-616 washers. This installation will prevent helm bearing from twisting too far, yet provide adequate movement.

NOTE: Previous installation may have contained one large AN960-916 washer next to the balljoint. This washer must not be reinstalled, the AN960-716L smaller and thinner washer described above is used as a replacement.

c. Rotate the emergency gear extension handcrank to obtain the 1.56 dimension (See Figure 5-14). Adjust the retraction tubes so they can be slipped in place with zero preload.

d. The bell crank is now in the gear down-and-locked position (green light on). Now adjust main gear retraction tubes so that the main gear rigging torque is between 240 and 280 inch pounds (refer to figure 5-11). The difference in left and right gear torque should register within 25 inch pounds of each other. Adjust nose gear retraction bungees so that they have a deflection of 0. 060 inch in the down-and-locked position (Refer to paragraph VF2 and figure 5-14, items 2 and 3). e. Position limit switch striker arm so that the gear-down light switch has just closed (green light on); secure the striker arm in this position. The gear is now rigged for the gear- down position with allowance for overrun of the actuator after cutoff. f. With all gear doors disconnected, run the gear up until the main gear is 0. 13 inch from the bumper pad. Position the gear-up limit switch striker arm so that the switch has just closed, then secure the striker arm in this position. The red gear-up light is now on and the gear is properly rigged in the gear-up position. g. Extend gear to down-and-locked position. Adjust gear door linkage (Refer to paragraph VD Ih VD 3 for door rigging instructions). Cycle the retraction system through at least two trouble-free test operations. Manually extend gear and recheck nose and main gear pre- load for limits specified inparagraph d. above. The gear is now properly rigged and ready for use.

The ailerons, flaps elevators, and rudder are of all-metal construction. They are jig-built, using hinges of machined e?L~rusions. The elevator and rudder incorporate an unusual method of construc- tion. The leading-edge spar of these controls consists of a specially designed extrusion that allows flush attachment of the skin. Lead counterweights are provided for dynamic balancing to prevent flutter.

Push-pulltubes, rather than the conventional cable system, are used to actuate the controls. Rod end bearings are used throughout the control system. These bearings are simple and dependable and require very little maintenance.

I. Introduction.

in and a. The purpose of this section is to assist service and maintenance personnel testing calibrating the SIooney PC System. Table 2 lists the most probable troubles that may be encountered and the procedures to be taken to isolate and correct the cause of malfunction. that Table 2 Para. 9 provides a step-by-step procedure for system analysis in the event does not cover the Drocedure.

b. Reference should be made to paragraph 3 (Ground Test Procedure) for ground checking of the unit for proper vacuum settings, leaks, and command functions. Reference should be made to paragraph 5 (Operating Instructions) for proper iii-flight checking and setting of the unit.

c. This section deals primarily with the two-axis PC system. Sc h made to tile. D~ertial Pitch Control (elevator control) system or to the hiagnetic i-leading Lock, as both of these systems are dealt with in a separateOperationh Service Manual,

2. System Description.

a. General

The system is a pneumatically operated two-axis automatic-control device, which sanses both roll and yaw while deriving its power from the aircraft engine-driven vacuum pump. The system consists basically of a gyro-sense element which meters vacuum pressure to a cylinder-piston servo assembly. On all aircraft in which this system is installed, these servos are attached to the aileron and rudder controls, providing for a dual-control system.

~ZOTE: The 1967 and subsequent ~IZOC,E F models have a turn coordinator which replaces the rate ~ro and operates by vacuum and electrical power simultaneously. The turn coordinator also replaces the turn-and-bank indicator in these models.

b. Operation

I. Stability and control of the airplane about both the roll and yaw axes is Lbtained by tilt- ing the rate-gyro (or turn coordinator) assemblyto a predetermined angle. This permits a part of the roll rate and a pan of the yaw rate to act on the sensitive gyro-rotcr ele- ment, producing an output signal. In this manner, a singlegyro elemant :s sensing motion about two axes-roll and yaw-the~eby providing basically a two-axis system.

2. Roll or y~y of the airplane caused by wind gusts, out-of-trim conditions, or airspeed changes displaces the rate gyro (or tum coordinator). The resulting output signal is coupled to a spool-sleeve rotary valve. The spool is rotated'inside the sleeve in pro- portion to both yaw and roll rates of the airplane. The spool moves to a location be- tween the vzcuum-su_Dply port and one of the outputports. The other output port is qDened to atmosphere, bleeding the vacuum. The resulting vacuum differential is cirec- red to the proper pneumatically operated servo so as to correct the original roll or yaw error. In straight-and-level flight,, the vacuum differential is zero and the servos are balanced.

3. Desired roll and yaw rate proportions of the total si~al are obtained by mounting the rate ~ro (or turn coordinator) at a predetermined incline angle from truehorizontal at cruise attitude. Changes in this angle, due to changes in the pitch attitude of the air- plane, orily partially compensate for the corresponding change inaircraftstability characteristics. For instance, as the aircraft pitches up to climb, the decreased air- speed and lower aerodynzmic loads necessitate more aileron control motion to main- tain stability. The corresponding change in rate-gyro (or turn coordinator) tilt angle produces increased roll-rate sensitivity, which partially compensates for the change in aircraft stability. The opposite occurs as the airplane pitches down and airspeed in- creas es.

REVISED NOVEMBER 1966 6-17

Island Enterprises 4. Provisions have been made in this system to allow for a roll trim pilot command func- tion. This roll trim may be used to compensate for asymmetrical fuel and passenger loading and to optimize system performance in climb, cruise, and letdown configura- tions. During normal aircraft operation in low-speed climb, it is necessary to utilize a combination of right rudderlaileron control to maintain wings-level flight. Dispiac- ing the roll-trim knob to the right will partially compensate for this condition. Like- wise, during high-speed descent the normal left rudderfaileron trim required may be accomplished by displacing the roll-trim valve to the left. However, the application of the roll-trim valve is not intended to substitute for proper rigging of the aircraft control system.

5. If the aircraft is properly trimmed by means of roll-trim adjustment, the unit will main- tain an average heading over a fairly long period of time; however, the unit will not maintain an absolute preselected heading without the addition of a magnetic heading lock. For optimum performance the aircraft must be rigged to fly needle-hall (or turn co- ordinator) centered.

6. The system push-button disconnect, located in the control wheel, operates a pneumatic relay which provides vacuum to the gyro-sense element (or turn coordinator), When the push button is depressed, all servo vacuum supply is relieved and the system is im- mediately inoperative. The pilot may then command turns in the normal manner without overriding the system. Releasing the push button reactivates the system. However, normal maneuvers may be readily accomplished without disengaging the system, as over-power forces recluired are small and no damage will result to either the aircraft or the system.

c. System Performance.

The Mooney Lateral Stability Augmentation System is designed to be capable of maintaining aircraft ecF~ilibrium over the o_Derational speed range under conditions that would otherwise cause rapid spiral divergence. The device is also intended to maintain lateral stability and prevent excessive changes in heading and airplane gyrations in turbulent air.

3. GroundTest Procedure.

Perform the following ground tests and procedures after completion of component replacement and prior to starting engine or conducting flight tests:

a. All vacuum lines must be free of kinks and sharp bends. Make certain that lines have been purged or blown free of foreign panicles before operating the system. NOTE: Do nor operate the system at any time with lines disconnected From servo units. do Also, not fly aircraft with servo unit bibs capped or lines plugged when they are connected to servo units. Expansion within servo cylinder can block movement of ailerons when aircraft is flown to altitude.

b. AircraftVacuum (PrimaryVacuum)

the Stan engine and increase the rpm to 1700 (If desired, an external vacuum pump may be utilized if the vacuum source is attached to the engine side of the aircraft vacuum relief in. valve.). Adjust the vacuum-relief valve to 4.75 4 .25j Hg. on the gyro horizon or directional gyro case. The primary vacuum reading on the PC system will be approx- imately 1/2 in Hg. lower than that read at the ~ro horizon (See ~ig. 6-15 and Fig. 6-17, Sheet 2, PC 3.). ~Iake cenainthatthe vacuum relief valvl ·sl!d regulator arefunctioning properly. NOTE: The vacuum-relief vdlve setting shoula bemaintained onthehigh side of the limit.

CAUTION

Permit no oil, grease, or thread lube, etc. to enter internal parts of the dry vacuum pump. Clean all lines before reinstallin,o. Do notusethreadlube on fittings.

3. By mouth, apply about 5 in. Hg suction. Valve should not leak more than 2 in. Hg in 30 seconds.

4. Depress valve and vacuum should drop immediately, proving that tubes in control wheel and valve are not restricted.

5. Upon release of valve, burton should return immediately to its normal position.

d. PilotValve-Operation

The pilot valve is in effect a pneumatic relay that shuts off the vacuum supply to the rate gyro valve (or Nm coordinator) when cutoff valve is depressed and at the same time relieves the vacuum in the servos so that the system does not load the controls when system is cut off.

Hg. 3, For further Group I and Group III autopilot maintenance information covering 1965 8 1966 models, refer to Operation Service Instruction manuals 11968-1 (Mooney Nzv-couplerfHeading Lock) and 11968-2 (Mooney Pitch Control). Manuals 11990-1 and 21990-2 cover 1967 and subsequent models.

4. Replace the test bib caps and make certain that no leaks exist around these caps. Manually displace the roll-trim knob counter-clockwise as far as possible, ~he control wheel should tend to turn to the left. Turn the roll-trim valve fully clock- wise and the control wheel should tend to turn to the right. Center the roll-trim valve. During taxi operations the control wheel will tend to turn opposite to the air- craft if the ~ro is properly phased. 4. Roll-Yaw System.

a. Rate Gyro Val~e Cencermg (1965 1966 models) Vacuum differential may result from the rate-gyro valve be~ing off center while the aircraft is stationary on the ground. Yawing the aircraft will precess the rate gyro. In this manner it may be deten?ined whether or not the pneumatic null is permanently offset. If there ap- pears to be a permanent offsk to the right or left, greater than a .2 in. Hg differential, the rate-gyro valve should be repositioned. Only minute movements of the valve stub are re- quired. b. Roll-Trim ValveCenterin,o

rorr Roll trim valve stops are factory adjusted and should not be moved. The knob should be centered (dot at top) with same degree of rotation right and left (Fi~re 6-17, Sheet 2, PC 3).

NOTE: 1967 C, E 8 F models have a turn coordinator which has a roll-trim knob on the in- strument front. If the turn coordinator is removed (rec~iring removal of the knob), the knob should first be centered for ease of relocation.

a. The following tests are to~ be conducted as directed in Table 2. As each of the tests is con- ducted, the reading or indication should be if, in any test, the reading differs from the correct indication, follow the corrective measures as indicated.

In the event that malfunctions are not covered specifically in Table 2, the following tests should be used as a step-by-step procedure for thorough system analysis.

b. Test #I-Vacuum Settings

Start the engne and increase the rpm to 1700 gJhen desired, an external vacuum pump may be utilized if the vacuum source is attached to the engine side of the aircraft vacuum-relief valve~.

Adjust the aircraft vacuum-relief valve to produce 4.75 Hg(-I-.25 in. Hg) output as read at the case of either the ~ro horizon or directional gyro (See Figure 6-15 and Figure 6-17, Sheet 2, PC 3.). Always adjust to the high side of the limit.

c. Test 32-Vacuum Line and Servo Leak Test

Visually inspect all lines to eliminate possible defects such as kinks, restrictions. or obvi- ous breaks.

Disconnect line from the back of the gyro sense element and install vacuum-test gauge in the open end of the line (See Figure 6-15 and Fi~re 6-17, Sheet 2, PC 2.!. Rotate aircraft controls so as to extend the piston of the respective servo. This will provide a vacuum in the system which may be read off of the test suction,azuge. Hold the control surfaces solid- ly. making certain that the piston is stationary. If no leak in the system exists, the test suction gauge reading will remain constant. Exercise care that all tubing connections are d~t and will not produce a leak. When checking that tubing which connects to the roll-trim valve, they must be removed from the valve and securely plugged. The valve has atmosphere- bleed ports which preclude this leak test unless the tubing is plugged.

Li· TeSt~3-GyrOROtOT Speed

Refer to Figure 6-15i\. Attach a 0-10 in. Hg vacuum gauge to test bib,U1. With the vacuum relief valve set as described in paragraph 3.b., a reading of approximately 4.25 in. Hg should be obtained at this point. This reading will vary depending upon the setting within the coler- ance of 1.75 in. Hg (+.25 in. Hg).

UncaD rest bib 82 as shown in Figure 6-15A and Figure 6-17, Sheet 2, PC 2, and attach a line from the vent side of the suction gauge to test bib f2. Adjust the set screw called out in Fi~re d-15A andfigure6-17, Sheet 2, PC 2 to a reading of 3 in. Hg(f.5 in. Hg, -0 in. Hg!.

e. Test ~d-Rate GyroValveCentering

Refer to Figure 6-16. (1965 1966 models). Disconnect red and green tubing from back of rate ~ro. Attach a differential gauge across~the two·bibs and rotate valve until a 0 in, dif- ferentialis obtained.

Yaw aircraft and note needle deflection on differential gauge indicating rate gyro deflection. When aircraft stops yawing. gyro should come back to center within ~.2 in. Hg. The rate EIY'O O' Nm coordinator should be replaced if it does not center properly.

REVISED NOVEMBER 1966 6-25

Island Enterprises f. Test ,U5-lnstallation Inspection

Rotate the aircraft controlwheel. The attachment to the respective servos must be tig'nt and the servo piston extended with rubber seal not stretched (See Figure 6-17, Sheet 3, PC 8.).

Examine the primary control system to determine that no excessive friction exists. Lubri- cate all hinge points as-depicted in Figure 2-9.

Also refer to Figure 6-17, Sheet 3, PC 4 when trouble shooting system. Be sure the chain between the aileron bell crank and the aileron servo does not have a twist. This can be corrected by repositionin,o the rubber boot on the servo.

Refer to Figure 6-17, PC 2. 3, ·i. 5, 6, 7. and schematics for proper line routing and color coding.

FUEL SYSTENI

Island Enterprises SECTION VII FUEB. SYSTEM

A. GENEIUL

The fuel system consists of inte,oral sealed fuel cells located in the front portion of each wing. These cells feed to a selector valve which includes a strainer and sump drain. From the selector, fuel is fed to the electric boost pump, engine-driven pump, and then to the carburetor or fuel injector.

13. TROUBLE SHOOTIf*TG

Troubles peculiar to the fuel system are listed in Table 3 along with their probable causes and sug- gested remedies. When trouble shooting, check from the power supply'to the items affected. if no trouble is found by this method, the trouble probably exists inside individual pieces of dcluipment; which may be removed from the aircraft and an identical unit, tested and known to be in good con- dition, should be installed in place.

a. Sealant Material Characteristics:

1. Application life is the time that the mixed compound remains suitable for application. Application life is always based on standard conditions of 750F and 50~ relative humidi- ity. For every 100F rise in temperature, application life is reduced by half, and for every 100F drop in temperature, application life is doubled. High humidity at the time of mixing shortens the application life.

2. Maximum unopened container storage life is six (6) months at 850F.

2. Kits consisting of the proper proportions of base compound and accelerator should be used.

3. Slowly stir, to avoid excessive air entrapment, the accelerator into the base compound and thoroughly mix approximately seven to ten minutes. Be sure to scrape the sides and bottom of the container in order to include all compound in the mixture and to in- sure uniform blending. Scrape mixing paddle periodictillg to remove unmixed compound.

7-4 REVISED JULY1980

Island Enterprises 4, Take a small amount of sealant from the mixture with a clean alumnium strip and spread the sealant, then visually examine the film of sealant to ascertain if the accelerator is visible in particle form. If particles of accelerator: are visible, continue the mi~ing operation. If coarse particles of accelerator persist after mixing, the mixed batch and rem~iTlinP- accelerator willbe rejected.

5. Put a small amount of sealant in the accelerator container and mix to assure that all of the accelerator is mixed into the sealant.

4. Sealant applicationIns~uctions.

The following instructions are for the reapplication of sealant removed in order to repair tank leaks.

a. BrushSeakant

1, Apply a brush coat of sealant compound PR1422-A 1/2, A2 or CS3204-A 1/2, A2 over seams, rivets, nuts, and bolts if removed for repair.

2. A one-inch stiff paint brush is recommended for this operation. Brush strokes should be parallelto seams forcing the sealant into all gaps. Use a circular brush action to deposit an even coat of sealant around rivets, and bells. Coat should be approx- imately 1/32 of an inch thick.

3. Coll3iderable brush action should be used to force sealant into all small crevices to ob- tain good adhesion. Air pockets trapped under the sealant due to improper application will open up in the form of a hole or void soon after it has been applied. Repair should be made by pressing the sealant in place with 9 spatula while it is still in the applica- tion life state.

4. In cases where the to_D of a fla~ge is .040 inches or less and where application of a suc- cessful fillet would not be clearly defined, apply two brush coats of sealant compound in appro~imately 1/32 inch thick coats. Allowfirst coat to cure approximately four hours or until it becomes nibbery before application of the second coat. The second coat should extend 1/4 of an inch past the previous coat.

b.

1. Generdl Req~rirements.

a. Filleting sealant (PR1422-B 1/2, B2 or CS3a04-lj 1/2, B2) must be tack free.

b. See Figure 7-5 for typicalfillet size.

c. Filleting sealants laid on intersecting joints shallbe joined together to produce a continuous fillet.

d. All and hard to reach areas should be sealed first, to prevent the possibil- ity of their being overlooked or incorrectly sealed.

b. If an extrusion gun is used, hold ~un perpendii~ular to seam when applying filletirSo compound so that extruded sealant will be packed tightly.

c. Use a spatula to pack sealant firnilv in place; work out air pockets and properly form each fillet.

c, Protective Coating Procedure (Brush).

i. Brush on a smooth, coat of PR 1005-L over sealant with a paint brush short, even strokes. The fihn should extend one inch beyond the sealant on td the ad- jacent metal.

2. Allow the top coat to cure 20 minutes at 750F or until tack-free.

d. Senli~P of Removable Panels.

I. General Req~ements,

a. Clean metal surfaces to be sealed with Turco 657 Wipe Solvent or M.E.X. Do not allow solvent to dry on surface; wipe off to prevent redeposit of con- taminants.

b. Cleaned surfaces need dry only 5~to 10 min~rtes before application of sealant. Sealant should be applied as soon as possible after cleaning.

c. Parts should not be stored or handled in any manner which will allow fingerprints, dust, dirt, and other foreign substances to contaminate the surfaces to be sealed after the cleaning operation.

2. Sealin~g·Procedure (for upper right wing-walk access panel).

a. Apply a coat of access door sealant PR1422-B 1/2 or CS3204-B 1/2, B2 to either faying surface using a short,stiff bristle brush, spatula or filleting gun. If the gun is used for application, the sealant must: be smoothed with a brush or spatula.

b, Cover the entire faying surface with a sealant coat of sufficient thickness (1/32 to 1/'16 inch) to assure extrusion along the edges of the faying surface when the mating parts are assembled.

c. Assemble parts immediatelq- after application of sealant, tighten screws to obtain, as near as possible, a metal-to-metal contact.

a. Apply a coat of 3R1403-G-~2 to either faying surface using a stiff, short bristle brush, be a spatula, or filleting gun. If a gun is used for application, the sealant, must smoothed with a brush or ssatula.

b. Cover the entire faying surface with a sealant coat of sufficient thickness (1/32 to 1/16 inch) to assure extrusion along the edges of the faying surface when the mating parts are assembled.

c. Assemble parts immediately after application of sealant; tighten screws to obtain as near as possible a metal-to-metal contact.

d. After fastener installation, remove the extruded sealant from the wing surface.

5. Description of Leaks.

It is important to make careful periodic fuel tank inspections. These inspections are particularly important in co~fined areas of the airplane which are not exposed to air stream in flight. Classification of fuel leaks, which occur in both confined areas and open areas, is necessnrv to differentiate between those leaks which require repair be- fore flight and those which do not constitute a flight hazard. The wetted area around a leak is an indication of the intensity of the leak. All leaks should be mar~ed and the location and intensity of the leak should be recorded.

a. Classification of Leaks as to Intensity and to Location.

1. Classification as to intensity (See Figure 7-2).

a. Stain is a slow fuel seepage which tends to dry as it is exposed to the air.

b. Seep: A seep is a fuel leak which reappears in a short period of time after being wiped clean.

c. IIeavy seep: A fuel leak which appears immediately after being wiped clean.

d. Running leak: A leak which nows steadily.

2. Cbassficationasto Location.

of the a. Slow to heavy seeps occurring in open areas, such as the surfaces leaks wing or wheel well which are exposed to the air stream in flight, are which do not constitute a flight hazard. Such leaks need not be repaired before flight, provicling the condition causing the leak cannot result in a leak: of greater intensity after a flight is in progress. Seeps considered permissible for flight should be inspected frequently to see that an increase in tensity has not occurred.

b. Leaks which constitute a flight hazard.

1. A leak and any leak in a confined area not exposed to the air stream should be repaired before the next flight. (See Fi~ure 7-3.)

6. Leak Detection.

a. External LeakDetectionAfter Fueling.

1. To be able to trace the leak from where it appears on the o~rter boundary to its true source inside the tank, the exact point where the fuel is escaping from the tank must be determined. Locating this point will help determine from which fitting or seam the leak originates. and crevices 2. By usi~ an air gun to blow and evaporate fuel from the seams the tank of the leak area, the exact point where the fuel is escaping from may be more clearly defined.

Island Enterprises 3. Small seep leaks can be traced with the raw edge of torn paper. The Fuzzy edge of torn paper adsorbs fluid and gives a good visual indication of the presence of any fuel when brought in contact with suspected leak points.

4. After the leak has beentraced to its exterior source and marked, drain fuel from tanks.

b. Internal LeakDetection.

1. It is very important that the true source of the ir~terior leak be found in order to make a permanent repair. The fuel tank is a network of seams, and fuel may flow through or along a seam, or from one seamto another and may channel a few inches or several feet to the point where it appears on the external boundary of the tank.

2. Enter the tank thro~h the top inspection plates only (see Figure 7-3) and illspect the sealant in the general area of the o~rtside leak point. Look first for bare seams, rivets, and bolts in difficult-to-seal areas. Inspect sealant for blisters, pin holes, cracks, splits, and loss of adhesion. Mark all flaws with masking tape.

3. Test each flaw inside the tank with 20 to 30 PSIair Cfiltered) line pressure by holding the air nozzle against the flaw and check the o~rtside leak point closely for sjo~s of fuel.

4. After testing allflaws inthis manner, and if no leak source has been dis- covered, apply bubble fluid to outside of tank and again apply air pressure to flaws inside of tank.

5. See Figure 7-4 for suggested method of leak detection when a leak is sus- pected around a rivet or when the above mei~hods have been unsuccessful.

7. Leak Repair Procedure.

a. Temporary Repair of Fastener Leaks.

1. Generally all leaks located in enclosed areas and runnino leaks in open areas constitute a flight hazard. Fastener leaks in these categories ma~ be repaired temporarily by the application of a sealant fillet over the fas- tener head on the fuel tank exterior.

2. In order for satisfactory temporary repair of a leak to be made at a fastener, structural integrity must exist in the area of the leak.

3. Temporary repair procedure for fastener leaks.

a. Remove sufficient fuelto drop the fuel level below the leak.

b. Clean the head of the fastener and the adjacent surface with Turco 657 t~ipesolvent orequivale~t anddrythroughly. Fastenerheadand adjacent met~ must be free)from paint, dirt, and oil.

c. Apply 1/8 inch thick coat of PR 1422-B 1/2, B2 or CS3204-B 1/2, B2 over the head and around the fastener.

d. Cure the sealant untilfirm and rubbery.

e. Refillthe tombs and carefully examine the repair periodically. If leak reoccurs, remove the sealant and either make a new temporary repair or make a permanent repair.

REVISED JULY 1980 7-11

Island Enterprises b. Permanent LeakRepair.

1. If the leak source is determined to be around a rivet or threaded fastener, the repair procedure shall be to restriki the rivet or retorque the fastener to the maximum torque valve permitted. Any rivet can be resttck only once. If the leak continues, the rivet must be replaced. Repair any sealant damage due to the restriking or retorquing operation.

2. Remove sealant in immediate area of leak source using a sharp non-metalic tool; a chisel-shaped formica tool is suggested. Bevel or slope end ends of existing sealant so that the new sealant canform a continuous and smooth tie-in.

3. Thoroughly clean repair area using a metal cleaning solventto allowgood adhesion. Wash one small area at a time. Then dry with a clean cloth before the solvent evaporates to prevent redisposition of oil and dirt on the surface. Always pour the solvent on the washing cloth to prevent contamination of the solvent supply.

4. Cleaned area must be thoroughly dried by blowing filtered air over the im- mediate area until there is no possibility of solvent or fuel entrapment under adjacent sealant.

5. Apply sealant as required for repair (See Figure 7-1). Repaired fillets must be blended into existing fillets and worked with a filleting tool as required.

6. Allow all repaired sealant to cure to, a tack-free condition, and apply two brush coats of PR 1005-L to the repaired area.

7. Recheck for leaks by applyinp; a coating of Turco leak detector to the outside of the sealed tank with the rank cap and vent closed as the tank is pressure tested with 2 psi of filtered air for a minimum of 30 minutes. Do not exceed 2 psi pressure. Leaks uiill-be indicated by the presence of bubbles in the Turco leak detector.

ThebatteryontheMzoE&F Is located aft of the baggage compartment and is accessible through the radio access door.

of the instrument The master switch for the electrical system is located at the top I~ft-hand side panel.

B. TROUBL~ SHOOTING

Malfunctions peculiar to the electrical system are listed in Table 6 along with their causes and sug- pested remedies. When trouble shooting, check from the power supplyto the item affected. If no trouble is found by this method, the trouble probably exists inside an individual piece of ec[uipment known to be which may then be removed from the airplane and an identical unit or units, tested and good. installed in its place.

I. ElectricalSwitches andCircuitBreakers.

Electrical switches and circuit breakers, located in the lower left and lower right instrument panels, control the navigation and instrument lights, landing light, electric turn-and-bank indi- cator, electric fuel pump, and other electrical components. The circuit breakers automatically break the electrical circuit if an overload is applied to the system, thus preventing damage to the electrical wiring. To reset the circuit breakers, simplypushinthebuttons. Allowsuf- ficient time for cooling before resetting circuit breakers. When a circuit breaker has tripped a second successive rime, the cause of the overload should be determined prior to attempting to reset the circuit breaker.

2. Battery.

The battery should be maintained in a fully charged condition at all times, and the water level should be checked at regular intervals; never add anything but distilled water. Do not overfill as the electrolite will overflow and corrode the belly of the airplane. A hydrometer check should be performed periodically to determine the percent of charge presentin the battery (Refer to Table 5~. A fully charged battery will not freeze. All connections must be kept clean and tight. If the battery is not uD to normal charge, recharge, starting with a rate of four amperes and fin- ishing with two amperes. When cleaning the battery care must be exercised to avoid contamina- tion of the electrolyte.

REVISED NOVEMBER 1966 8-1

Island Enterprises NOTE: Quick charges are not recommended.

3. Battery ChargingSystem.

The charging rate of the battery depends upon the condition of the battery and the voltage regu- lator setting. With all loads off and the engine running at 2000 rpm or higher, the normal battery charging rate will be 5 to 35 amperes.

if the charging current is considered excessive, check the following:

a. Charging rate should slowly drop to 10 amperes or less after 15 to 20 minutes of flight.

NOTE: A very low battery will take longer to show a drop in charging current.

b. Too high a voltage regulator setting will cause excessive heating and loss of water.

NOTE: Measure the voltage with a voltmeter at "Batt" terminal of the voltage regulator. At 800 F., the voltage should be 13.8 to 14.8. This voltagewill behigher if the temperature is less than 80" F, and loner if the temperature is higher than 80" F.

If charging rate is low, check the following:

a. The charging rate of a fully charged battery is normally from 1 to 4 amperes.

b. The regulator should not be considered defective because ofalowchargingrateuntil:

i. A voltmeter check indicates that the voltage at the''Batt" terminal is below require- ments given in NOTE above.

2. A hydrometer check of the battery indicates that the battery is not fully charged. Refer to Table 5 for hydrometer reading vs. battery charge percent.

4. Voltage Regulator.

Island Enterprises SECTION IX INSTRUMENTS

A. GENERAL

The instrument panel has been designed to provide functional location of all flight, radio, and engine instrument groups.

All flight instruments are grouped on a shock-mounted panel directly in front of the pilot. They are located in such a manner as to provide maximum efficiency for instrument cross-check, a most im- portant item for IFR flying. A radio panel is located in the center of the instrument panel and has sufficient room for tworadios. The glove compartment slot serves as a mounting area for a third radio. All of the engine instruments are grouped on the co-pilot's panel.

B. TROUBtE SHOOTIE~G

When trcuble shooting instruments having an electrical power source, check from the power supply to the instrument affected. If no malfunction is found, the trouble probably exists inside the individual instrument. The instrument then should be replaced by an identical instrument, tested and known to .be operating properly. See Table 7 for instrument trouble shooting procedures.

10-4 REVISED NOVEMBER 1966

Island Enterprises H. ELECTRIC GEAR. INSPECTION (OPTIONAL INSTALLATION)

Raise aircraft on jacks to allow operational testing of both the electrical and emergency gear ex- tension systems. (Refer to Section V-R.).

An 80 mph air pressure equivalent must·he applied to the pitot tube orifice to activate the airspeed pressure switch to permit retraction of the gear. Attach a Ii-inch length of 3/8-inch plyable rubber hose eurgicaltubing) over the pitot tube end and pinch the open end of the tube with a cotter pin. Rotate the coffer piri zmtil the compressed air within the rolled tube activates the airspeed pressure switch (located in the cabin near the hydraulic reservoir). Then raise the gear electrically.

Refer to page 5-23 for emergency gear extension instructions (Manual Operation of th~ Electrical Landing Gear System). Test emergency gear extension. Do not retract the gear with the emergency handcrank; to do so will damage the flexible drive shaft.

Thoroughly inspect and lubricate both the electrical and emergency gear extension systems (See Lubrication Diagram, Figure 2-9 for proper lubricant)

The drive connector should be removed from the actuating motor and inspected for a worn or stripped f~male spline. Clean and Lubricate the motor worm gear.

Test the drive connector to check for proper functioning.

NOTES

If the pilot experiences difficulty with gear extension or retraction, ~he gear system should be lubri- cated and the malfunction corrected before the next flight.- Raise the aircraft on jacks, locate and correct the trouble, and cycle-test gear operation. Refer to page 5-23, Section H, paragraph 3 for periodic lubrication and inspection specifications for the electric gear system actuator.

Always make certain the handcrank is fully disengaged before operating the gear electrically.

In trouble shooting the system, remember that a binding or maladjusted gear door may overload the actuating system. Remove the belly panels to examine the knife disconnects under the floor boards for loose or faulty connections. An electrical overload in the system can be discovered by connecting an ammeter in the motor circuit (red wire leading from the actuating motor to the electric fuel pump circuit breaker) beneath the floor boards. Open the red wire knife disconnect and connect the ammeter poles to the disconnect terminals. During gear extension, the ammeter should read 15 to 18 amp; during retraction, 25-30 amp. An amperage reading exceeding the max- imum indicates a faulty motor or electrical circuit and/or a binding in the gear action due to impro- per rigging or misalignment of the gear actuator and its mounting bracket.

Dual waroi~ horns (1967 ON models) replace the landing gear-throttle warning horn and prestail indicator installed on 1962-1966 models.

Island Enterprises 2. Procedures

a. For urliformity of finish appearance, prepare only entire skin panels for repainting. First, clean the area to be repainted with the solvent-type cleaner. Wipe on, then wipe off cleaner with cheese cloth or clean towels until surface is dry. Second, sand areas to be painted as needed-start with No. 400 grit (wet or dry) and finish with 600 to 800 grit. Third, reclean entire area to be painted with the solvent-type cleaner, wipe clean, and mask-off adjoining areas that will not be painted.

b. To fill dents, use a flexible plastic welding compound (bodyputty or aerodynamic filler). Carefully follow instructions printed on the container.

c. All spray-applied paints must be mixed in a one-to-one proportion(50-50) with their ap- propriate thinners. When using a large compressor unit and re,oulator, maintain a 60 PSI spraying pressure and be sure intake air is properly filtered. A portable spray pot should be set to maintain a 40 PSI minimum spraypressure. Work only in a dust and moisture controlled painting area.

d. Use a face respirator to prevent inhalation of paint dust. It is recommended that the work- man apply a li~t coat of vaseline to his hair and exposed skin to allow easy removal of paint stains with a mild soap solution

e. Always test-spray a new paint mixture on masking paper before proceeding with the appli- cation. Hold the spray nozzle eight to ten inches from the surface. Spray in cross patterns with verticdl stroke movements first and then withhorizontal movements over the same area.

f. Apply vinyl-chromate primer mixed with vinyl-type reducer to newly installed unpainted skins. Apply one coat of appropriately thinned gray primer (Enmar filler) to previously painted surfaces that have been properly prepared for repainting. Allow primer to dry run- free, then spray three coats of the properly mixed finish paint.

g. All acrylic enamel paints have a tendency to "orangepeel" when sprayed too close to the panel or when the paint viscosity is too high. The ~tddition of an equal pan of burn-down thinner to the thinned finish paint will eliminate orange peel effect due to improper thinning.

h. Apply three coats of white base and/or color finish allowing three to five minutes between coats depending upon weather conditions. Allow five to ten minutes between coats in cold, dry weather; in humid weather, each coat should dry in fifteen minutes.

i. Do not thin acid-resistant black paint or exterior finish touch-up paint for brush-on appli- cation. Use a small round watercolor brush trimmed to a point for ap~lication of undiluted touch-up paint to small scratches and bare spots. A handy rack for touch-up paint storage can be made from babyfood jars mounted in a wooden rack.

Island Enterprises C. CORROSION DETECTION PREVENTION

Most metalic fabrication materials are susceptible to corrosion. Corrosion may occur an aircraft in any climate, but it will be a problem more often in areas where the aircraft is exposed to salt air or high humidity, or where there are industrial contaminants in the armosphere. The aircraft should be Inspected frequently to detect and correct corrosion before serious damage occurs.

I. Types of corrosion.

Corrosion normally appears in one or more of four forms. Eacb type of corrosion can be pre- cluded or controlled by a preventative maintenance program.

a. Chemical corrosion

Chemical corrosion normally occurs where battery acid or exhaust gases come in contact with metalsurfaces. A few simple precautions will prevent chemical corrosion.

1. Be sure that the battery vent is free from obstruction at all times.

2. All scratches and worn spots, found in areas painted with acid-resistantpaint, should be repainted at once.

3. If acid is spilled on metal surfaces, flush the entire area with sodium bicarbonate add water. The solution should be rinsed away at once and the area dried by driving all water from crevices with an air hose before wiping the surface dry with a clean cloth.

4. Frequently clean exhaust gas deposits from metal surfaces.

b. Local-cell corrosion

Local-cell corrosion is easy to detect. On baremetal surfaces, in an early stage of develop- ment, it appears as a light, wfiitish powder deposit. Surface pits warn of advanced local- cell corrosion. On painted surfaces, the first indication of corrosion will be evidence of paint blistering.

Any form of corrosion should be removed at once upon detection. If it is necessary to re- move paint, only an approved aircraft paint remover should be used. Care should be taken that paint removing substances are not allowed to remain in metal crevices, for this will cause further corrosion. Turco 2662(3 or 3002 will remove corrosion and treat the metal surface in one application.

c. Concentrationcell corrosion.

Corrosion forming under rivet heads, along faying surfaces, or at skin to longeron contact surfaces is called concentration cell corrosion. Detection recFdres close inspection. Rivets must be removed and skin laps must be separated to remove concentration cell corrosion. Use aluminum wool soaked in kerosene to scour corrosion deposits from the surface before painting both fayin,a surfaces with zinc chromate primer and reassemblying.

d. Galvanic corrosion

Galvanic corrosion sometimes occurs between dissimilar metals such as stainless steel and aluminum. To remove this form of corrosion, separate the pans, remove the corrosion, and paint both surfaces with zinc chromate primer before reassembling.

Further recommended procedures for corrosion control areoutlined in Turco Products Tech- nical Data Bulletin g184. Write Turco Products. inc., P.O. Box 1055, Wilmington, California.

11-4

Island Enterprises 2. Hints onpreventingcorrosion.

a. Thoroughly examine unpaimed metal surfaces at inspections and check corrosion when found. Carefully examine seams, lap joints, and crevices wheremoisture or dirt can collect. Areas exposed to exhaust gases require frequent inspection and cleaning.

b. Corrosion may attack metal even though the surface is painted. Inspect painted areas for a blistered or scaly appearance that warns of corrosion below the paint layer.

c. Use only aircraft detergents to wash the exterior airframe. Cover vent scoops whenthe aircraft is being washed. Rinse the exterior after exposure to salt air or industrial fallout.

d. Since moisture promotes corrosion, areas where water is apt to collect must be inspected thoroughly and frequently. Use an air hose to drive water from crevices before wiping the exterior surface dry after washdown.

e. Hangar the aircraft when not in use.

f. If battery acid is spilled on any part of the aircraft, wash the area immediately with a solu- tion of sodium bicarbonate in water. Rinse with water and dry with clean towels.

3. Zincchromating.

Zinc chromating internal surfaces of the airframe will greatly retard corrosion. However, chromating will not eliminate the necessity of periodic inspection aimed at detection of trouble s_aots, especially in those areas where it is impracticableto apply zinc chromate (skin laps, fayings, etc.). If deep corrosion is found, it should be removedby sandingwith emery cloth of approximately 320 grit. Aluminum etching compounds are not recommended for corrosion removing, because they cannot be readily neutralized.

1. Cleaning

a. Pour a portion of the cleaning fluid into the safety mixing can.

b. Wipe the area to be cleaned with a clean rag dipped in the cleaning fluid.

c. Wipe the cleaned area with a rag dipped in the cleaning solvent. The entire area to be painted should be cleaned before application of the primer.

CAUTION: Wipe solvent is toxic and flammable. Do not smoke within 25 feet of the exposed solvent. Force air through the painting area and use only explosion-proof lights.
